He was born in Russia and took an undergraduate degree from Moscow University before moving to the US in 2004. His hobbies include chess and table tennis, and he’s developed a couple interesting Arduino-based gadgets to help him hone his skills.

The robot features a ball bin, hopper, and dual friction-wheel design not unlike commercial serving machines for tennis and squash. Sorokin has also developed a special chess timer for the popular four-handed, two-board Bughouse variant.
